I am trying to remove the immo from a BMW E46 318i ecu with bosch #0 261 204 420
BMS 46 ecu from Bosch product finder.
I used a software that removes the immo from the psop44 prom on the backside of the board but no
luck.
Would I also need to flash the main chip?
The ecu in the car is dead so got my hands on a used one.

Swap the psop between the ECUs, the immobiliser code is in there.

Hi all,
who please help to me find ISN from this ECU, I can´t read this via INPA on the bench.
In attachment are completly data from EWS and DME.
From EWS I found ISN but in DME I can´t find ISN manually in this unit.
Many many thanks for help.
In EWS is ISN: 0d27
